In order to more clearly disclose the construction, operation and use of the invention, reference should be had to the accompanying drawings forming part of the present application.

Throughout the several figures of the drawing, like reference characters designate the same parts in the different views.

In the drawing:

Figure 1 is a side elevation;

Figure 2 is a perspective view, applied;

Figure 3 is an elevation of a rope section with the spacing sleeve in place;

Figure 4 is a plan view of Figure 3; and

Figure 5 is a fragmentary longitudinal cross section of Figure 1, on line 5-5.

The radial width of the shoulder 8, it will be. noticed, is approximately that of the radial thickness of sleeve 1, so that the outer edge of shoulder 8 and the outer face of sleeve 7, when assembled, are in substantial alignment. The lower end ill of the spiral blade is made by cutting substantially diametrically across the spiral 9 and rounding off the corners. The edges of the blade end should be smoothed or rounded to avoid all possible damage to the rope fibers when the tool is being used, as will hereinafter appear.

The operation of the invention is as follows: Therope in which the splice is to be made is firmly held or secured in any suitable manner and the assembled tool, as in Figure 1, is inserted at the desired point, the end l0 making the en-- ,videsajsimple' frictional holding'device.

trance. By applying pressure and turning blade 9 as you would a cork screw, the blade will follow through between the strands, spreading them apart to the diameter of shoulder 8 and sleeve 1. As the tool continues through the rope, the sleeve 1 and enclosed shank 4 will be between the rope strands "with, the :ends of sleeve 1 extending at opposite sidesalof'. the rope. When this point is reached, the rod and handle I and Z are withdrawn from one end of sleeve 1 and the shank 4 with blade 9 are withdrawn from the opposite end.

Many changes maybe made'in'the'construction; arrangement and disposition of the various parts of the invention within the scope of the appended claims without departing from the field of the invention'and it is meant to include all such within this application wherein only one preferred form has been illustrated by way of example and with no thought or intention of, in and degree, limiting the claims thereby,

Having thus described m invention, what I claim and desire to protect by Letters Patent is:

l. A rope splicing tool comprising a handle provided with a. concentrically disposed socket extional area as that of said socket removably mounted in said socket in non-revoluble relation to said socket, said shank being provided with a radially extending shoulder disposed at a. distance from the adjacent handle end,in assembled relation, and a tubular sleeve removably, mounted on said bit shank between said shoulder and said adjacent handle end.

2. A rope splicing tool comprising a handle provided with a concentrically disposed socket ex tending longitudinally into one end thereof, a bit shank of substantiall the same cross sectional "area as that of saidsocket removably mounted in said socket in non-revoluble relation to said socket, said shank being provided with a radially extending shoulder disposed at a distance from g the adjacent handle end, in assembled relation, a tubular sleeve removably mounted on said bit shank between said shoulder-and said adjacent handle end and means'carried by-said-bit shank and yieldingly engaging the adjacent innr' wall of the aforesaid socket;
